what do you mean using the whole original music video?
and how can the copyright claim change? and it will change to what?
Like a music video like [youtube]http://www.youtube.com/watch?v=eDuRoPIOBjE[/youtube]
You have to own it, or it could get taken down. It all depends on the content owner, he wants if off now, they'll tell you. If it changes it'll tell you to delete the video, if you don't delete it then Youtube will delete it and then you'll get one strike.
